The Masamoto "HC" series is made of pure Japanese Virgin Carbon Steel. The high carbon blade has extremely hard and sharp edge, but requires special care to avoid rusting and chipping. Well balanced Black pakka wood handle comes with a welded non-seam stainless steel bolster. We highly recommend the Masamoto Knives for your best cooking as well as GIFT for Anniversary, because it represents "The Premier Grand Gru" silently.
